Claims.

This invention relates to a warp dyeing beam head and more especially toa warp dyeing beam in which the flange portions on the proximate sidesof the heads over which a perforated cylinder fits are cast integralwith the heads and project a. substantial distance inwardly toward eachother and have a plurality of bosses cast integral with the flanges andwith the head, and the flanges being slotted longitudinally of theperiphery thereof, so that not only will the ends of the perforatedcylinder be amply supported, but also there will be a free flow of thetreating solution such as dyeing fluid, bleaching fluid, and the like,through the flange and through the extreme ends of the perforatedcylinder.

Warp beams are usually made with the heads from 28 to 32 inches indiameter and a perforated cylinder is usually from 8 inches in diameterto 24 inches in diameter. All of them are approximately 54% inchesbetween the heads. These beams are for dyeing warps or for bleaching thewarp threads wound on the beams and there is usually disposed on one ofthe beams about 400 pounds of yarn. This yarn is wound on the beams on awarper, the perforated beam cylinder riding down on the drum of thewarper at the beginning of the winding operation. This drum on which theperforated cylinder rests is to A of an inch shorter than the insidelength of the beam. By riding on the cylinder, the warper drum drivesthe beam and also gives the braking surface for stopping the cylinder ifan end breaks down. By driving the beam from the warper drum, the headsare hanging down, supported only by the ends of the perforated beamcylinder. These perforated cylinders have their perforations usually ofan inch in diameter on of an inch staggered centers but sometimes theseperforations vary in size as well as in the manner of disposition.Perforations have to be all the way to the ends of the cylinder in orderfor the yarn to dye properly or to bleach properly in the portions wherethe cylinder joins the beam heads.

Heretofore, it has been common practice to make a shoulder about /2 inchhigh, that is, an annular shoulder around the inside surface of the beamhead, and to assemble the cylinder over these annular projections orshoulders, and then suitable bolts or tie rods are passed through thebeam head and in the space inside the perforated cylinder to thus holdthe head and the cylinder in assembled relation. The perforatedcylinders are usually made of stainless steel or some othernon-corrosive material and are usually about of an inch thick. In thesevere service to which these beamsare subjected, running at about 500revolutions per minute on high speed warpers, and then suddenly stoppingwhen an end breaks down, the heads being supported by the cylinder,there is a tendency to stretch the cylinder at the ends so that theheads become loose.

It is an object of this invention to provide a warp dyeing beam having aperforated cylinder and head members with the head members having castintegral therewith annular rim portions projecting toward each other andover which the ends of the perforated cylinder are adapted to fit, theannular shouldershaving integral therewith and integral with the headscertain supporting members for strengthening and supporting the rims andthese rims are grooved peripherally down to the supporting bosses tothus allow a free flow of the treating fluid through the rims andthrough the perforations in the ends of the cylinders.

It is another object of this invention to provide a warp dyeing andbleaching beam comprising a pair of head members, cast from stainlesssteel preferably, and each of these head members has an annular rim onthe inside surface thereof and over which a perforated cylinder isadapted to be fitted, said rim and head member having integral therewitha plurality of supporting members integral with the interior surface ofthe rim and the shoulders extending further inwardly than as hasheretofore been the case to provide greater support for the ends of theperforated cylinder, and the annular shoulders having peripherallydisposed grooves running entirely around the rim portions and down tothe supporting bosses to thus allow. a free flow of treating fluidthrough the rim portions and through the perforations in the ends of thecylinders fitting over the rim portions.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings, in which Figure 1 is an elevation, with thecentral portion broken away, and showing one of the end portions insection of my improved warp beam;

Figure 2 is a reduced vertical sectional view taken along the line 2-2in Figure 1;

Figure 3 is an isometric view looking at the inside surface of one ofthe head portions and with the perforated cylinder removed therefrom;

Figure 4 is a sectional detail view taken along the line 4-4 inFig'ure2;

Figure 5 is an enlarged view similar to Figure 4 and showing the rimbefore the grooves are cut therein.

Referring more specifically to the drawings, the numeral It indicatesthe two head portions which are identical and these are preferably castfrom stainless steel. Each head portion has integral therewith, andprojecting from the inside surface thereof, an annular rim portion I lwhich has castlintegral therewith a plurality of reinforcing members orbosses l2. The middle portions of the heads have cross members I! and Ithus providing a plurality of openings i5 through which the treatingfluid may flow to the interior of the beam, or through which fluid mayflow out of the openings if the direction of flow is reversed.

The central portions of the heads ill have suitable bores l'l throughwhich supporting rods may be passed for holding the same. The heads alsohave a plurality of openings therethrough, through which may be passedbolts 20 for securing the heads inside the ends of a suitable cylinder2|. After the heads and the annular portions H have been cast integralwith each other, then one or more peripheral grooves or slots 22 aremilled to completely penetrate the annular portion II, but which do notpenetrate the reinforcing members or bosses i2. Then the annularportions II are inserted inside the ends of the cylinder 2| which has aplurality of perforations 24 through-' out its periphery and throughoutits length.

The heads on their exterior surfaces have annular portions .25 which areusually employed for fitting over a suitable opening in a bleaching ordyeing operation. The bolts 20 extend longitudinally inside the cylinder2| and have nuts 21 on their ends and whereby the heads are secured tothe ends of the cylinder 2 I.

If desired, the annular portions or rims I I may be cast with thegrooves 22 therein and thus dispense with milling or cutting the sameafter casting the head members.

In the drawings and specification there has been set forth 'a preferredembodiment of the invention, and although specific terms are employed,they are used in a generic and descriptive sense only, and not forpurposes of limitation, the scope of the invention being defined in theclaims.

I claim:
